A novel optical orthogonal frequency division multiplexing (OFDM) network coding scheme is proposed over passive optical network (PON) system. The proposed scheme for all-optical virtual private network (VPN) does not only improve transmission efficiency, but also realize full-duplex communication mode in a single fiber. Compared with the traditional all-optical VPN architectures, the all-optic...

For a long time the capability of wireless devices to be configured either as a transmitter or a receiver at a time was the norm. The invention of full duplex shattered this norm. Theoretically, given N-RF chains with full-duplex capability, if each one can be configured as a receiver or a transmitter, we should be able to generate N transmission modes. Can a system capable of utilizing all pos...

In this paper, we propose a full-duplex orthogonal frequency-division multiplexing (OFDM) deviceto-device (D2D) system in two-hop networks, where multiple full-duplex decode-and-forward (DF) relays assist the transmission from D2D user equipment (DUE) transmitter to DUE receiver. By such a transmission mechanism, the signal transmitted by the DUE transmitter does not need to go through a base s...

This paper introduces a systematic and novel mechanism for devising security attack in the WCN (Wireless Communication Network). The proposed model involves implementation of AD (Artificial Dust) by intruder, followed execution HD (Half-Duplex) attack. communication network is based on deployment urban rural scenarios with an unknown CSI (Channel State Information). Depending achieved path loss...

The demand for high speed data will be increased ever than before in fifth generation (5G) of wireless communication networks [1]. One of the most promising ways to increase data rate is to make the wireless cell smaller in size and densify the network with a large number of low power base stations (i.e., Small Cells). These small cells can increase the wireless data rate by providing higher qu...

The capability of nodes to transmit and receive data simultaneously within the same frequency band, referred as in-band FD, disrupts conventional assumptions underlying wireless network design. This new feature enhances spectral efficiency reduces latency, which are essential drivers in advancing next-generation networks. In past few years, full-duplex (FD) has evolved from being a laboratory i...
